Haworthia plant named &#39;New York&#39;

ABSTRACT

A new and distinct  Haworthia  cultivar named ‘NEW YORK’ is disclosed, characterized by unique spotted leaves, top and underside. The new variety has strong roots and faster than normal growth rate. The new variety is a  Haworthia , normally produced as an outdoor garden or container plant.

LATIN NAME OF THE GENUS AND SPECIES

Haworthia fasciata

VARIETY DENOMINATION

‘NEW YORK’

BACKGROUND OF THE INVENTION

The new Haworthia cultivar is a product of a planned breeding program conducted by the inventor, Rogier Willems, in Tielen, Belgium. The objective of the breeding program was to produce new Haworthia varieties for ornamental commercial applications. The cross resulting in this new variety was made between 1992 and 2008.

The seed parent is a unpatented, unnamed, proprietary seedling variety of Haworthia fasciata. The pollen parent is unknown, as the crossing resulting in ‘NEW YORK’ was an open pollination, with unidentifiable pollen parents. The new variety was discovered in July 2008 by the inventor in a group of seedlings resulting from the crossing, in a research greenhouse in Tielen, Belgium.

Asexual reproduction of the new cultivar ‘NEW YORK’ by tissue culture and vegetative cuttings was first performed at a research greenhouse in Tielen, Belgium in July 2008 and has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘NEW YORK’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘NEW YORK’ These characteristics in combination distinguish ‘NEW YORK’ as a new and distinct Haworthia cultivar:

1. Distinctive white spots pattern on foliage.

2. Stronger roots.

3. Rapid growth rate.

Plants of the new cultivar ‘NEW YORK’ are similar to plants of the seed parent in most horticultural characteristics, however, plants of the new cultivar ‘NEW YORK’ produce leaves with white spots on top and white dots on the underside, whereas the seed parent produces whites stripes top and underside of the leaf. ‘NEW YORK’ also has stronger roots and a faster growth rate than the seed parent

COMMERCIAL COMPARISON

Plants of the new cultivar ‘NEW YORK’ are similar to plants of commercial Haworthia fasciata in most horticultural characteristics, however, plants of the new cultivar ‘NEW YORK’ produce leaves with white spots on top and white dots on the underside, whereas Haworthia fasciata varieties known to the inventor produce whites stripes top and underside of the leaf. ‘NEW YORK’ also has stronger roots and higher growth rate than Haworthia fasciata varieties known to the inventor.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘NEW YORK’ grown in a greenhouse, in a 8.5 cm basket. Age of the plant photographed is approximately 11 months from a rooted cutting. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart 2001 except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘NEW YORK’ plants grown in a greenhouse in Tielen, Belgium. The growing temperature ranged from 18° C. to 28° C. during the day and from 13° C. to 18° C. during the night. General light conditions are bright, normal sunlight. Measurements and numerical values represent averages of typical plant types. Plants are approximately 11 months old from a rooted cutting.
